Last week or so volume controls have started acting erratic when controlling my yamaha reciever. Has worked fine for years, nothing has changed. Volume is unpredictable: sometimes goes up when down is pressed or scrolls all the way to mute when down is pressed or press up once and goes up 20 steps. Have re-paired, reset and restarted as well as trying another voice remote from a different room. Same issues so I do not believe the issue is the remote itself. Any ideas?
